Resolution method of multiple jammers for passive monopulse radar
-
摘要: 对同时进入单脉冲雷达主波束内的多个宽带噪声调频干扰源进行角度分辨是非常困难的,该文分析了单脉冲雷达接收机对宽带噪声调频干扰信号的响应,通过适当选择接收机带宽,使接收机输出的干扰脉冲分离,并通过测量瞬时角信息,用统计分析法分辨多个干扰源目标角度,计算机仿真证实了该方法的正确性和有效性。Abstract: It is very difficult to resolve multiple jammers in the mainlobe of a passive monopulse radar. This paper discusses monopulse radar response to noise frequency modulation (FM) jamming. By means of selecting proper receiver bandwidth, it makes jamming pulses (receiver output) separate. Then instantaneous angles of jammers are measured. These angles can be resolved by a statistic method. The method is verified with the results of computer simulation.
